High-Performance Sewage Treatment Chemicals for Water Treatment Ion Exchange Resin

Product Introduction:

Ion exchange resin is a polymer compound with functional groups (active groups that exchange ions), a network structure, and insolubility. Usually spherical particles. The full name of ion exchange resin consists of classification name, skeleton (or group) name, and basic name.

The pore structure is divided into gel type and macroporous type. Any resin with physical pore structure is called macroporous resin, and "macropore" is added before the full name. For those classified as acidic, add "yang" before the name, and for those classified as alkaline, add "yin" before the name. For example, macroporous strongly acidic styrene based cation exchange resin.

Product Usage:

1. Water treatment

The demand for ion exchange resins in the field of water treatment is high, accounting for about 90% of the production of ion exchange resins, which are used for the removal of various cations and anions in water. At present, the maximum consumption of ion exchange resin is used for pure water treatment in thermal power plants, followed by atomic energy, semiconductor, electronics industry, etc.

2. Food industry

Ion exchange resin can be used in industrial equipment such as sugar refining, monosodium glutamate, alcohol refining, and biological products. For example, the production of high fructose corn syrup involves extracting starch from corn, followed by hydrolysis reaction to produce glucose and fructose, and then ion exchange treatment to produce high fructose corn syrup. The consumption of ion exchange resin in the food industry is second only to water treatment.

3. Pharmaceutical industry

Ionic exchange resins in the pharmaceutical industry play an important role in the development of new generation antibiotics and the quality improvement of existing antibiotics. The successful development of streptomycin is a prominent example. In recent years, there have been studies on the commission of traditional Chinese medicine.

4. Synthetic chemistry and petrochemical industry

In organic synthesis, acids and bases are commonly used as catalysts for esterification, hydrolysis, ester exchange, hydration, and other reactions. Using ion exchange resin instead of inorganic acids and bases can also carry out the above reactions, and has more advantages. Resin can be reused repeatedly, the product is easy to separate, the reactor is not corroded, does not pollute the environment, and the reaction is easy to control. The preparation of (MTBE) uses macroporous ion exchange resin as a catalyst, which is formed by the reaction of isobutene and methanol, replacing the original tetraethyl lead that can cause serious environmental pollution.

5. Environmental Protection

Ion exchange resins have been applied in many highly concerned environmental protection issues. Currently, many aqueous or non-aqueous solutions contain toxic ions or non-ionic substances, which can be recycled using resins. Such as removing metal ions from electroplating wastewater and recovering useful substances from film production wastewater.

6. Wet metallurgy and others

Ion exchange resin can separate, concentrate, purify uranium and extract rare earth elements and precious metals from depleted uranium ore.
